Laryngitis is an inflammatory disorder involving the mucosal lining and underlying lamina propria of the larynx and vocal folds (true vocal cords). Subdivided by clinical duration into Acute Laryngitis (<3 weeks; most commonly a self-limiting viral infection or acute phonotrauma) and Chronic Laryngitis (>3 weeks; driven by chronic noxious exposures, laryngopharyngeal reflux, or persistent vocal misuse), it is characteristically defined by Dysphonia (alteration in vocal pitch, volume, or quality, presenting as a raspy, husky, breathy, strained hoarseness or complete vocal loss [aphonia]), localized laryngeal soreness, dry tickling throat clearing, and a dry hacking spasmodic cough. Because prolonged hoarseness can represent an early presentation of premalignant vocal dysplasia or invasive laryngeal malignancy, any unexplained dysphonia persisting longer than 3 weeks mandates direct visualization of the vocal cords via flexible laryngoscopy.
An acute or chronic inflammation of the laryngeal mucosa and vocal fold epithelium, resulting in hoarseness, reduced vocal loudness, throat irritation, and vocal fatigue.
Common causes
- Acute Viral Respiratory Infection: infection by common respiratory viruses (Rhinovirus, Adenovirus, Influenza, Parainfluenza, Coronavirus) producing acute vascular congestion and mucosal edema of the vocal folds
- Acute or Chronic Phonotrauma / Vocal Overuse: excessive shouting, singing, prolonged screaming, or incorrect vocal projection causing mechanical shear stress, localized microvascular hemorrhage, and vocal fold edema (nodules/polyps)
- Laryngopharyngeal Reflux (LPR / Silent Reflux): retrograde flow of gastric acid and digestive pepsin enzyme reaching the posterior laryngeal mucosa, triggering chemical inflammation, interarytenoid erythema, and pachydermia laryngis
- Chronic Environmental and Chemical Inhalants: active cigarette smoking, secondhand tobacco smoke, cannabis, vaping, occupational chemical fumes, and airborne industrial dusts
- Pharmacological triggers: Inhaled Corticosteroids (ICS; e.g., fluticasone, budesonide for asthma; causes localized steroid-induced laryngeal myopathy or secondary laryngeal candidiasis)
- Bacterial and Fungal infections: Moraxella catarrhalis, Streptococcus pneumoniae, Haemophilus influenzae, Bordetella pertussis, or Candida albicans (in immunocompromised or steroid inhaler users)
Risk Factors
- Professional voice users (teachers, public speakers, singers, trial lawyers, drill instructors, telephone operators)
- Active tobacco smoking or heavy chronic alcohol consumption
- Underlying Gastroesophageal Reflux Disease (GERD) or chronic rhinosinusitis with post-nasal drip
- Frequent or improper use of metered-dose inhaled corticosteroids without a spacer or post-inhalation mouth rinsing
- Coexisting upper respiratory tract infections and environmental dry climate
Common symptoms
- Dysphonia / Hoarseness: rough, raspy, strained, breathy, or low-pitched voice quality, or complete loss of voice (aphonia)
- Vocal fatigue: voice weakens or breaks after short periods of speaking
- Dry, scratchy, tickling throat discomfort prompting an irresistible, constant urge to clear the throat
- Dry, barking, hacking cough, often worsening at night or during speech attempts
- Mild odynophagia (painful swallowing) or a constant foreign-body 'globus' sensation in the throat
- Absence of inspiratory stridor, drooling, or dyspnea in uncomplicated viral laryngitis
Clinical Red Flags
Seek urgent medical attention at an emergency department or primary care clinic if you present with any of the following symptoms:
- Acute Epiglottitis / Supraglottitis: rapid onset of high fever, severe sore throat, difficulty swallowing, drooling, 'hot potato' muffled voice, and inspiratory stridor with the patient sitting upright and leaning forward in a 'tripod position' (life-threatening airway emergency requiring immediate 911 emergency dispatch, emergency airway equipment, and avoiding any invasive oral tongue-blade examination)
- Laryngeal Stridor and Impending Airway Obstruction: high-pitched musical sound on breathing in, intercostal/suprasternal retractions, and acute cyanosis (immediate emergency intubation/tracheostomy)
- Persistent Unexplained Hoarseness >3 Weeks: mandatory flexible laryngoscopy to rule out Laryngeal Squamous Cell Carcinoma, vocal cord leukoplakia, or thoracic tumor compressing the recurrent laryngeal nerve
- Hoarseness accompanied by Hemoptysis (coughing up blood), dysphagia, or a hard, painless palpable neck mass (cervical lymphadenopathy)
Lifestyle & diet support
Practice strict vocal rest (avoid speaking, shouting, and NEVER whisper; use pen and paper or smartphone messaging to communicate during acute flares), inhale warm plain steam for 10 minutes twice daily, drink plenty of room-temperature water throughout the day, avoid throat clearing (instead, take a sip of water or perform a silent hard swallow), avoid caffeine, mints, and alcohol which dry the vocal cords, elevate the head of your bed if acid reflux is present, and never smoke.
Treatment Approaches
Conventional Management
A comprehensive evidence-based vocal hygiene and medical protocol: (1) Mandatory Complete Vocal Rest: absolute avoidance of speaking, singing, and especially whispering (whispering exerts significantly higher mechanical friction and strain on the vocal fold adductor muscles than normal relaxed speaking). (2) Optimal Hydration and Humidification: drinking 2 to 3 liters of water daily and inhaling warm unmedicated steam or using cool mist room humidifiers. (3) Elimination of Aggravating Factors: treating underlying LPR with dietary antireflux precautions and Proton Pump Inhibitors (PPIs) / H2 blockers for 8–12 weeks; using a spacer device and rinsing the mouth thoroughly after inhaled steroid use; smoking cessation. (4) Antibiotics are strictly contraindicated in acute viral laryngitis (provide zero benefit and risk adverse drug events). (5) Short-term oral corticosteroids (dexamethasone / prednisone) are reserved strictly for professional performers needing urgent short-term recovery or severe inflammatory laryngeal edema.
Homeopathic Approach
Homeopathic constitutional and vocal-fatigue remedies (such as Argentum Metallicum, Causticum, Phosphorus, Spongia Tosta, Drosera Rotundifolia, Belladonna, Arum Triphyllum, Ferrum Phosphoricum, Lachesis Muta, Hepar Sulphuris Calcareum) serve as supportive care to ease laryngeal dryness, soothe hoarseness, and assist mucosal recovery alongside strict vocal rest, steam inhalation, and ENT evaluation.

Diagnosis & tests
Investigation Protocol
Diagnosed clinically through history and acoustic vocal evaluation in acute viral cases. In chronic cases (>3 weeks) or in patients with red flag features, the definitive gold standard diagnostic test is Flexible Fiberoptic Video-Laryngostroboscopy (performed by an Otolaryngologist / ENT: provides high-definition, slow-motion visualization of the vocal fold mucosal wave, vibratory amplitude, symmetry, closure patterns, and rules out vocal cord nodules, polyps, cysts, contact ulcers, granulomas, vocal cord leukoplakia, papillomatosis, vocal cord paralysis, and invasive laryngeal squamous cell carcinoma).
Differential Diagnosis
Differentiate Laryngitis from Acute Epiglottitis (life-threatening emergency: high fever, tripod posture, severe sore throat, drooling, inspiratory stridor, 'thumb sign' on lateral neck radiograph), Laryngeal Squamous Cell Carcinoma (persistent progressive hoarseness >3 weeks in a smoker/drinker with neck mass or otalgia), Vocal Cord Nodules / Polyps ('singer's nodes'), Vocal Cord Paralysis (unilateral recurrent laryngeal nerve palsy following thyroid surgery or thoracic malignancy), Spasmodic Dysphonia (laryngeal dystonia), and Croup (Laryngotracheobronchitis; pediatric barking seal-like cough and subglottic 'steeple sign').
